French Open: Andy Murray breezes through, Lopez stunned

Paris: British third seed Andy Murray, twice a semi-finalist, who took his clay record this season to 11-0 with a 6-3, 6-3, 6-1 win over Argentine 'lucky loser' Facundo Arguello.

Murray, with claycourt titles in Munich and Madrid, goes on to face either Canadian world number 53 Vasek Pospisil or Portugal's 44th-ranked Joao Sousa. "Always the first round of the majors is tough and it was quite windy and difficult conditions at the start," said Murray. "I was a little bit nervous at the start but I like that, it shows that you care and want to do well."

World number four Tomas Berdych, a 2010 semi-finalist, continued his solid claycourt season with a 6-0, 7-5, 6-3 win over Japanese qualifier Yoshihito Nishioka, the world number 146. Berdych will now face 36-year-old Davis Cup-winning teammate Radek Stepanek, who became the oldest man to win a match at Roland Garros since 38-year-old Jimmy Connors in 1991 when he saw off Croatian journeyman Ivan Dodig 5-7, 6-3, 6-4, 6-1.

Kokkinakis and Tomic will face off for a place in the third round where top seed Novak Djokovic will likely be waiting. Nick Kyrgios, the 29th-seeded Australian who beat Roger Federer in Madrid earlier this month, eased past Denis Istomin of Uzbekistan 6-3, 6-4, 6-3. Spanish eighth seed Carla Suarez Navarro, a quarter-finalist in 2008 and 2014, beat Romania's Monica Niculescu 6-2, 6-2.

German 11th seed Angelique Kerber, the champion on clay in Charleston and Stuttgart, needed just 50 minutes to brush aside Timea Babos of Hungary 6-0, 6-1. Former world number one Victoria Azarenka, who missed last year's Roland Garros through injury, marked her return by beating Spain's MarÃ­a-Teresa TorrÃ³-Flor 6-2, 6-1.

Croatia's Ana Konjuh, the youngest woman in the draw at 17, made the next round with a 6-1, 6-4 win over Russian qualifier Margarita Gasparyan. Four American women exited although they were guaranteed a winner later in the day when 34-year-old Venus Williams, playing in her 18th Roland Garros, was meeting Sloane Stephens. Meanwhile, a record was set in the clash between Denisa Allertova of the Czech Republic and Britain's Johanna Konta. Their first set tiebreak, which went 19/17 in favour of the Czech, was the longest in tournament history.
